The growing season in the alpine regions of the Rockies is very short, typically lasting only about 6-8 weeks due to harsh conditions.

Alpine regions in the Rockies, found above the tree line, experience extremely short growing seasons. Due to factors like low temperatures, persistent snow cover, high winds, and intense solar radiation, plants have a limited window of opportunity to grow and reproduce. This period usually lasts for only about 6-8 weeks during the summer months when temperatures are relatively warmer and snow has melted. This short growing season has led to unique adaptations in alpine plants.
